Abstract
The utility model discloses a resin groove for a quick laser forming machine. The resin groove comprises an equipment cabinet body (1), a resin groove body (2), a laser, a laser galvanometer, a power mechanism and a control system, wherein the resin groove body (2) is formed in the lateral lower side of the equipment cabinet body (1), and a liquid level detecting device is installed in the resin groove body (2); and the liquid level detecting device comprises a magnetic water ring (3) arranged in the resin groove body (2), a vertical rod (4) and a Hall sensor (5), wherein the magnetic water ring (3) is sleeved on the vertical rod (4), and the Hall sensor (5) is installed on the inner wall of the resin groove body (2) and is electrically connected with the control system. The liquid level detection in the resin groove is not interfered or affected by a liquid medium, so that the liquid level of the resin groove can be stably and reliably detected.
Description
Technical field
The utility model relates to the rapid shaping technique field, is a kind of resin storage tank for the laser fast shaping machine specifically.
Background technology
Laser fast shaping (SLA technology) also claims light chisel or stereolithography, is based on the photopolymerization principle work of liquid photosensitive resin.Photopolymerization reaction can take place rapidly in this liquid material under the UV-irradiation of certain wavelength and intensity, molecular weight sharply increases, and material also just changes from liquid to solid.Fill with liquid light-cured resin in the liquid bath, laser beam can scan on liquid surface under the deflecting mirror effect, and the having or not by computer control of the track of scanning and light, the local liquid that luminous point is got to just solidifies.When moulding began, workbench was in the next degree of depth of determining of liquid level, the instruction point by point scanning that the hot spot after the focusing is pressed computer at liquid level, i.e. pointwise curing.After one deck scanning was finished, not irradiated place was still liquid resin.Lifting platform drives the platform layer height that descends then, be covered with one deck resin on the in type aspect again, the resin liquid level that scraper plate is bigger with viscosity strikes off, and then descend the scanning of one deck, new one deck that solidifies is bonded on preceding one deck securely, so repeat to finish up to the whole part manufacturing, obtain a three-dimensional entity model.
Resin storage tank is installed on laser fast shaping pusher side below, is used for the splendid attire liquid resin.The lifting position of web plate is relevant with the liquid level of liquid resin in resin storage tank, and liquid resinous liquid level has important effect to the operation of rapid shaping simultaneously.Therefore liquid level sensor all is installed in the resin storage tank of prior art, is used for measuring liquid level and liquid level information is transferred to controller.The general infrared sensor of the liquid level sensor of prior art, utilize infrared irradiation to come the height of induction level, but infrared induction is relevant with the characteristic of resin, infrared sensor can produce the insensitive situation of induction for the operative liquid resin, it is inaccurate to cause liquid level to detect, and reliability is low.
The utility model content
The technical problems to be solved in the utility model is, provide a kind of liquid level detect sensitive, be used for the resin storage tank of laser fast shaping machine reliably.
Technical solution of the present utility model is, a kind of resin storage tank that is used for the laser fast shaping machine of following structure is provided, comprise rack body, resin storage tank, laser instrument, laser galvanometer, actuating unit and control system, resin storage tank is arranged on the side-lower of rack body, in the described resin storage tank liquid level detection device is installed; Described liquid level detection device comprises the magnetic water wing that places in the resin storage tank, vertical bar and Hall element, and described magnetic water wing is placed on the vertical bar, and described Hall element is installed on the inwall of resin storage tank, and is electrically connected with control system.
Adopt above structure, the utility model compared with prior art has the following advantages: adopt the utility model, designed the liquid level detection device based on Hall effect, can by the magnetic water wing along with liquid resinous liquid level rises or descends, and Hall element is sensed the change in location of magnetic water wing, thereby the signal of telecommunication of liquid level is transferred to control system, and then realizes the detection of liquid level; Liquid level of the present utility model detects not interference and the influence of liquid body medium, can reliablely and stablely detect the liquid level of resin storage tank.
As improvement, described Hall element has a plurality of, and a plurality of Hall element in the vertical directions are sequentially arranged on the resin storage tank inwall; Owing at differing heights Hall element is set all, liquid level detects more accurate.
As improvement, the top of described vertical bar is provided with for the positive stop spacing to the magnetic water wing; This design can prevent that the magnetic water wing from coming off from vertical bar.
Description of drawings
Fig. 1 is the structural representation of the resin storage tank for the laser fast shaping machine of the present utility model.
As shown in the figure 1, the rack body, 2, resin storage tank, 3, the magnetic water wing, 4, vertical bar, 5, Hall element, 6, positive stop.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, resin storage tank for the laser fast shaping machine of the present utility model, comprise rack body 1, resin storage tank 2, laser instrument, laser galvanometer, actuating unit and control system, resin storage tank 2 is arranged on the side-lower of rack body 1, in the described resin storage tank 2 liquid level detection device is installed; Described liquid level detection device comprises the magnetic water wing 3 that places in the resin storage tank 2, vertical bar 4 and Hall element 5, and described magnetic water wing 3 is placed on the vertical bar 4, and described Hall element 5 is installed on the inwall of resin storage tank 2, and is electrically connected with control system.
Described Hall element 5 has a plurality of, and a plurality of Hall element 5 in the vertical directions are sequentially arranged on resin storage tank 2 inwalls; A plurality of Hall elements 5 are electrically connected with control system respectively.
The top of described vertical bar 4 is provided with for the positive stop 6 spacing to magnetic water wing 3.
Operation principle of the present utility model is as follows: liquid level detection device of the present utility model is the liquid level detection device based on Hall effect, can on vertical bar, rise or descend along with liquid resinous liquid level by the magnetic water wing, the Hall element that is contained in the resin storage tank inwall is sensed the change in location of magnetic water wing, thereby the signal of telecommunication of liquid level is transferred to control system, and then realizes the detection of liquid level.
Below only be described with regard to the utility model preferred embodiment, but can not be interpreted as it is limitations on claims.The utility model not only is confined to above embodiment, and its concrete structure allows to change.In a word, all various variations of doing in the protection domain of the utility model independent claims are all in protection domain of the present utility model.
